It appears that I can successfully use DNS names in the haproxy.cfg file such as in: acl valid_sources hdr_ip(X-Forwarded-For) server.goo.com (where server.goo.com resolves to a single IP address, say, 1.2.3.4).
But if I update the DNS entry for server.goo.com to say, 10.20.30.40, I can't see any way to get haproxy to discover the new IP address. The DNS TTL is 5 minutes, and I restarted haproxy after I was sure the haproxy server's DNS cache had expired and haproxy was still fixated on the 1.2.3.4 address. So, is there something I'm missing? Or do I need to just use IP addresses? Thanks, Mitch Gerdisch
